●Product handling
Installation
•Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
IP65 protection cannot be guaranteed if the screws are not tightened to the specified torque.
•If a large manifold valve is mounted, lift the unit so that stress is not applied to the connecting part while
transporting.
The stress may cause breakage of the connecting part. The unit may become very heavy depending on the
combination. Transportation/installation shall be performed by multiple operators.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the SI Unit and/or input or output module can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the SI Unit and/or input or output module can malfunction due to interference of noise and surge voltage
from power and high voltage cables to the signal line.
Route the wires (piping) of the SI Unit and/or input or output module separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the Fieldbus system is
incorporated into equipment.
Otherwise noise can cause malfunction.
Environment
•Select the proper type of protection according to the environment of operation.
IP65 protection is achieved when the following conditions are met.
(1)The EX245-SPN1A/EX245-SPN2A and/or input or output module are connected properly with power/fieldbus
cable with Push Pull connector and I/O device cable with M12 connector.
The EX245-SPN3A and/or input or output module are connected properly with power cable with 7/8 inch
connector, fieldbus cable with M12 connector and I/O device cable with M12 connector.
(2)Suitable mounting of each unit and manifold valve.
(3)Be sure to fit a waterproof cap on any unused connectors.
If using in an environment that is exposed to water splashes, please take measures such as using a cover.
Do not use in an environment where moisture or water vapor are present. Otherwise failure and malfunction can
result.
•Do not use in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even
for a short time, it may be adversely affected (damage, malfunction etc.).
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment generating large surge near the unit (magnetic type lifter, high frequency inductive furnace,
welding machine, motor, etc.), this can cause deterioration of the internal circuitry element of the unit or result in
damage. Take measures against the surge sources, and prevent the lines from coming into close contact.
- 9 -
No.EX※※-OMW0011-A
•When a surge-generating load such as a relay, valve or lamp is driven directly, use a product with a
built-in surge absorbing element.
Direct drive of a load generating surge voltage can damage the product.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
•Prevent foreign matter such as dust or wire debris from getting inside the product.
•Mount the product in a place that is not exposed to excessive vibration or impact.
Otherwise failure or malfunction can result.
•Do not use the product in an environment that is exposed to temperature cycle.

For details of each setting, refer to the SI Unit Operation Manual.
•Please refer to the IO Controller manufacturer's manual etc. for details of programming and addresses.
For the IO Controller protocol and programming refer to the relevant manufacturer's documentation.
Maintenance
•Turn off the power supply, stop the supplied air, exhaust the residual pressure and verif y the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
•Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
•After maintenance is complete, perform appropriate functional inspections.
Stop operation if the equipment does not function properly.
Otherwise safety is not assured due to an unexpected malfunction or incorrect operation.
•Do not use solvents such as benzene, thinner etc. to clean each product.

3.2.1. Power/Bus connection
The SI Unit has two Power connectors (XD1/XD2) and two PROFINET communication
connectors (XF1/XF2). If only one connector is used, cover the unused connector with a seal cap so
that the protection rating of IP65 is maintained.
The supply for the logic/sensors “US1” and the supply for the valves/loads “US2” provide the
connected modules and the valve coils via the SI Unit.
The two supplies are isolated electrically and can be switched independently.
Caution
・ Seal caps must be fitted to all unused bus & power connector ports to ensure an IP65 rating.
・ Seal caps must be fitted to all unused bus connector ports to prevent eye exposure to the light
beam from the SCRJ connectors for the EX245-SPN1A
・ Power and bus lines must be installed correctly.
・ To prevent manifold components of the SI Unit from being damaged the supply lines for the
electronics and for the load voltage must be protected externally with a fuse.
・ Maximum loop through current between power connectors on each SI Unit must not be
exceeded.
・ The EX245-SPN1A makes use of a CLASS 1 LASER product. Do not stare into beam visible at
XF1/XF2.

3.2.2. FE terminal
The SI Unit must be connected to FE (Functional Earth) to divert electromagnetic interference. The
FE terminal and the FE pin of the two power connectors (XD1/XD2) are internally connected. Please
connect at least one of these three FEs to ground potential. For maximum protection the FE cable
should be as thick and short as reasonably possible. If it is difficult to shorten the power cable, it is
recommended to use the FE terminal screw.
3.2.3. Sensor/Load connection
Regarding the wiring of each module, refer to following section:
・ EX245-DX1 : Section 7.3
・ EX245-DY1 : Section 8.3

4.1. Configuration
The SI Unit is a modular station that consists of several modules. Setup your PROFINET IO
Controller’s software to reflect the configuration of your system.
4.1.1. GSD file and symbol files
In order to configure the SI Unit with your PROFINET IO Controller’s software the appropriate GSD
file is required. The GSD file contains all of necessary information to configure the SI Unit on your
PROFINET IO Controller’s software.
In order to represent the SI Unit in your PROFINET IO Controller’s software the appropriate symbol
files are required.
Current GSD file and symbol files name are as follows.
・ GSD file : GSDML-V2.3*-SMC-EX245-SPN-********.xml
・ Symbol files: GSDML-0083-0011-EX245.bmp
4.1.2. Head modules
The GSD file contains the description for two Head modules and three SI Units.
